Polymer nanocomposites have been attracting attention among researchers as electrical insulating application from energy storage to power delivery. However, partial discharge has always been a predecessor to major faults and problems in this field. In addition, there are a lot more to explore as the characteristic of partial discharge in nanocomposites is not clearly understood as well as the electrical properties of the nanocomposites. By adding a few amount of weight percentage (wt%) of the nano fillers, the physical, mechanical and electrical properties of polymers can be greatly enhanced. This is due to its amazing characteristic of having large specific area as a consequential from its nano sized particle that could enhance the electrical properties of the insulator. For instance, nano fillers in nanocomposites such as silica (SiO2), alumina (Al2O3) and titania (TiO2), play big role in providing good approach to increase dielectric breakdown strength and partial discharge resistance of nanocomposites. Such polymer nanocomposites will be reviewed thoroughly in this paper based on previous experimental works and studies. This paper provides reviews from related publications from year 1997 to 2011 including the results of experimental works which have been conducted by the authors with main focus on partial discharge characteristics in polymer nanocomposites, which demonstrates that research and utilization of polymer nanocomposites has well developed from past decades and will possess a high demand in future as electrical insulating material.

Nanofiller Content

<p>Insulation materials can be tailored by compounding nanofillers and polymer materials. The advantageous changes in properties of polymer nanocomposites can be explained by the large interface area of the nanofillers. Theoretical models developed in the field of nanodielectrics concentrate on the analysis of the interface volume.<br />Dielectric breakdown strength (DBS) is one of the most important properties of an insulation material. The DBS of nanocomposites depends heavily on the nanofiller content and even small quantities can cause improvement. This is linked to the maximum interface volume achieved already at low nanofiller concentrations. Homogeneous nanodispersion is the key for DBS increase and reliable results. Often the most profitable nanofiller quantities are below 5 wt-%. The same kind of behaviour can be seen with different voltage shapes, but with dc voltage the increase is bigger. DBS has a maximum value with respect to nanofiller amount and decreases thereafter. Filler quantities around 5 wt-% and even lower are the most attractive considering DBS of nanocomposites.</p>

High Dielectric

High dielectric polymer nanocomposites are promising candidates for energy storage applications. The main criteria of focus are high dielectric breakdown strength, high dielectric constant and low dielectric loss. In this study, we investigate the effect of the addition of TiO2 particles to PVDF matrix on the dielectric constant, breakdown and energy density of the system. The dispersion of the particles is qualified by scanning electron microscopy (SEM). The morphology of the composites is characterized by polarized light microscopy, Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). The dielectric properties are measured by a Novocontrol system with an Alpha analyzer. Finally, the breakdown measurements are carried out by a QuadTech hipot tester.

Academic Review

Polymer nanocomposites have recently been attracting attention among researchers in electrical insulating applications from energy storage to power delivery. However, partial discharge has always been a predecessor to major faults and problems in this field. In addition, there is a lot more to explore, as neither the partial discharge characteristic in nanocomposites nor their electrical properties are clearly understood. By adding a small amount of weight percentage (wt%) of nanofillers, the physical, mechanical, and electrical properties of polymers can be greatly enhanced. For instance, nanofillers in nanocomposites such as silica (SiO2), alumina (Al2O3) and titania (TiO2) play a big role in providing a good approach to increasing the dielectric breakdown strength and partial discharge resistance of nanocomposites. Such polymer nanocomposites will be reviewed thoroughly in this paper, with the different experimental and analytical techniques used in previous studies. This paper also provides an academic review about partial discharge in polymer nanocomposites used as electrical insulating material from previous research, covering aspects of preparation, characteristics of the nanocomposite based on experimental works, application in power systems, methods and techniques of experiment and analysis, and future trends.

Modification Of The Surface

The attack, on the surface of a polymer, by the atomic, molecular and ionic species that are created in a low pressure electrical discharge in a gas is interesting because: 1) significant interior morphological features may be revealed, 2) dielectric breakdown of polymeric insulation on high voltage power distribution lines involves the attack on the polymer of such species created in a corona discharge, 3) adhesive bonds formed between polymer surfaces subjected to such SDecies are much stronger than bonds between untreated surfaces, 4) the chemical modification of the surface creates a reactive surface to which a thin layer of another polymer may be bonded by glow discharge polymerization.
